Hey all, I haven't seen any discussion about the new Raid Class 6 mission (RC6 M4) in BF JP (/u/Sebachoo where?!). To be fair, it isn't too difficult to overcome, so I guess there's not many details to look out for. In any case, I've decided to write one.

Note: English translation may be wonky. I'm using the mighty power of Google Translate for assistance, so please bear with me on the errors. :P

COMMENTARIES

• As can be seen, this encounter is an AoE-heavy fight. Common attacks deal damage to at least 2-3 units. You will want to have a squad that can have a hell of a time (pun intended) handling all the constant damage.

• Positioning is key to this encounter. In addition to all the AoE damage, powerful attacks that target specific positions are common: "Astral Line", "Star Drive", and "Cross Radiation". Assuming the top row units in your squad are A and B, middle row as C and D (Friend), and bottom row as E and F, "Astral Line" hits ACE or BDF, "Star Drive" hits CD, and "Cross Radiation" hits CBF, so C is pretty much the target for all three attacks.

• You will want someone who has sufficient bulk in the middle frontal row (position C). For example, Krantz (ES provides chance to reduce damage to self when attacked), Paris (LS provides chance to reduce damage to 1), or Dolk (LS nulls elemental weakness to all party members and ES nulls crit for self). Defensive Spheres are generally recommended as well. Unfortunately, there's not much you can do with the Friend's position, so pick someone that'll give you the most bang for your buck. You can change the position of your squad in battle by going to Menu > left button on the bottom row.

• Burst healing and gradual recovery are both recommended (Will, Elza, Krantz).

• Dark units are generally not recommended, particularly in the front-row middle position. Some are pretty good though (not in the center position), like Les-Viola (Leader Skill reduces Light damage) and Elza (ES provides damage > HP drain and SBB can apply Curse and Injury).

• High-damaging attack to watch out for is "Supernova", which can be deadly when combined together with "Corrosive Corona", "Judgment", and/or the positional attacks. "Supernova" can be periodically prevented by applying Curse on the Main Body.

• "Void-sealed World" is the signature attack for all RC6 bosses. Am-Yunos's version wipes all buffs before activation, so it's going to be extra painful. Fortunately, it appears to be used only once the Scepter is destroyed. Curse prevents the activation, but once Curse wears off, it is triggered.

• You may think maybe having single-target nukers focusing on the Main Body is good, but you will have to destroy the Scepter if you want the rare material. Just remember to use mitigation (UBB recommended) and guarding when the Scepter is nearly destroyed (especially when your other team members keep on nuking).

• Overall not a tough fight. Just remember to position your units accordingly and it shouldn't be too much issue.
